DETAILED DESCRIPTION

Turning now to the drawings, systems and methods for operation of an anti-sandbagging hybrid game are illustrated. In several embodiments, an anti-sandbagging hybrid game is a form of a hybrid game that integrates both a gambling game that includes a real world engine (RWE) which manages the gambling game, as well as an entertainment game that includes a game world engine (GWE) which manages the entertainment portion of a game, and an entertainment software engine (ESE) which executes the game for user entertainment. In certain embodiments, the anti-sandbagging hybrid game also includes a user interface associated with either or both the gambling game and the entertainment game.

In operation of an anti-sandbagging hybrid game, a player acts upon various types of elements of the entertainment game in a game world environment. Upon acting on some of these elements, a wager is triggered in the gambling game. In playing the entertainment game, using the elements, a player can consume and accrue game world credits (GWC) within the entertainment game. These credits can be in the form of game world objects, experience points, points, etc. Wagers are made in the gambling game using real world credits (RC or RWC). The real world credits can be credits in an actual currency, or may be credits in a virtual currency. Gambling outcomes from the gambling game may cause consumption, loss or accrual of real or virtual credits. In addition, gambling outcomes in the gambling game may influence elements in the entertainment game such as by restoring a consumed element, causing the loss of an element, restoration or placement of a fixed element, etc. Example elements include enabling elements (EE) which are elements that enable a player's play of the entertainment game and may be consumed during play and may also be replenished during play within the entertainment game. Other types of elements include actionable elements (AE) which are elements that are acted upon and may not be restorable during normal play of the entertainment game.

Various hybrid games are discussed in Patent Cooperation Treaty Application No. PCT/US11/26768, filed Mar. 1, 2011, entitled “ENRICHED GAME PLAY ENVIRONMENT (SINGLE and/or MULTI-PLAYER) FOR CASINO APPLICATIONS” and Patent Cooperation Treaty Application No. PCT/US11/63587, filed Dec. 6, 2011, entitled “ENHANCED SLOT-MACHINE FOR CASINO APPLICATIONS” each disclosure of which is hereby incorporated by reference in its entirety.

In many embodiments, an anti-sandbagging hybrid game utilizes an anti-sandbagging so that entertainment game play of the anti-sandbagging hybrid game is fair to the player(s) of the anti-sandbagging hybrid game irrespective of player skill level at the entertainment game. The anti-sandbagging module can employ handicaps to entertainment game play to ensure that both less and more skilled players can derive a normal level of pleasure and progress in entertainment game play and that there is a fair amount of competition between players of different skill levels in head to head play of the entertainment game. In certain embodiments the anti-sandbagging module only monitors entertainment game play to ensure fair game play of the anti-sandbagging hybrid game irrespective of player skill level at the entertainment game. In particular embodiments the anti-sandbagging module monitors the entire anti-sandbagging hybrid game, such as by factoring in random outcomes in the entertainment game due to payouts from the gambling game, to ensure fair play of the entertainment game irrespective of player skill level at the anti-sandbagging hybrid game.

In several embodiments, an anti-sandbagging module ensures fair game play irrespective of player skill level by assigning rankings to each player of the anti-sandbagging hybrid game based upon player performance measurements and by assigning handicaps based upon each player's rankings. In certain embodiments, player performance measurements are based upon a player's performance results from head to head play against opponents. In particular embodiments, player performance measurements are experience points for game attributes from which a player's ranking can be derived.

In numerous embodiments, an anti-sandbagging module monitors a player's performance during entertainment game play after an initial player ranking is assigned to handicap the player if the player has significantly deviated from the player's expected performance at the entertainment game. In certain embodiments, statistical analysis using a player's current performance measurements and historical performance measurements are used determine if the player has significantly deviated from expected performance at the entertainment game. Anti-sandbagging hybrid games in accordance with embodiments of the invention are discussed further below.

Anti-Sandbagging Hybrid Games

In many embodiments, an anti-sandbagging hybrid game integrates high levels of entertainment content with a game of skill (entertainment game), a gambling experience with a game of chance (gambling game), and a fair game play experience irrespective of player skill level with an anti-sandbagging module. An anti-sandbagging hybrid game provides for a random outcome independent of player skill while providing that the user's gaming experience (as measured by obstacles/challenges encountered, time of play and other factors) is shaped by the player's skill. An anti-sandbagging hybrid game in accordance with an embodiment of the invention is illustrated in FIG. 1A. The anti-sandbagging hybrid game 128 includes a RWE 102, GWE 112, ESE 120, gambling game user interface 122, entertainment game user interface 124 and an anti-sandbagging module 126. The two user interfaces may be part of the same user interface but are separate in the illustrated embodiment. The RWE 102 is connected with the GWE 112 and the gambling game user interface 122. The ESE 120 is connected with the GWE 112 and the entertainment game user interface 124. The GWE 112 is connected also with the entertainment game user interface 124. The anti-sandbagging module 126 is connected with the GWE 112.

In several embodiments, the RWE 102 is the fundamental operating system for the gambling game of the anti-sandbagging hybrid game 128 and controls and operates the gambling game. The operation of a gambling game is enabled by money, such as real funds, accretes and declinates real gambling credits based on random gambling outcome, and whose gambling proposition is typically regulated by gaming control bodies. In many embodiments, the RWE includes a RW operating system (OS) 104, random number generator (RNG) 106, level “n” real-world credit pay tables (Table Ln-RWC) 108, RWC meters 110 and other software constructs that enable a game of chance to offer a fair and transparent gambling proposition, and to contain the auditable systems and functions that can enable the game to obtain gaming regulatory body approval.

A random number generator (RNG) 106 includes software and/or hardware algorithm and/or processes, which are used to generate random outcomes. A level “n” real-world credit pay table (Table Ln-RWC) 108 is a table that can be used in conjunction with a random number generator (RNG) 106 to dictate the real world credits (RWC) earned as a function of game play and is analogous to the pay tables used in a conventional slot machine. Table Ln-RWC payouts are independent of player skill. There may be one or a plurality of Table Ln-RWC pay tables 108 contained in a gambling game, the selection of which may be determined by factors including (but not limited to) game progress a player has earned, and/or bonus rounds which a player may be eligible for. Real world credits (RWC) are credits analogous to slot machine game credits, which are entered into a gambling game by the user, either in the form of money such as hard currency or electronic funds. RWCs can be decremented or augmented based on the outcome of a random number generator according to the Table Ln-RWC real world credits pay table 108, independent of player skill. In certain embodiments, an amount of RWC can be required to enter higher ESE game levels. RWC can be carried forward to higher game levels or paid out if a cash out is opted for by a player. The amount of RWC required to enter a specific level of the game “level n” need not be the same for each level.

In many embodiments, the GWE 112 manages the overall anti-sandbagging hybrid game operation, with the RWE 102 and the ESE 120 effectively being support units to the GWE 112. In several embodiments, the GWE 112 contains mechanical, electronic and software system for an entertainment game. The GWE 112 includes a GW game operating system (OS) 114 that provides control of the entertainment game. The GWE additionally contains a level “n” game world credit pay table (Table Ln-GWC) 116 from where to take input from this table to affect the play of the entertainment game. The GWE 112 can further couple to the RWE 102 to determine the amount of RWC available on the game and other metrics of wagering on the gambling game (and potentially affect the amount of RWC in play on the RWE). The GWE additionally contains various audit logs and activity meters (such as the GWC meter) 118. The GWE 112 can also couple to a centralized server for exchanging various data related to the player and their activities on the game. The GWE 112 furthermore couples to the ESE 120.

In many embodiments, a level “n” game world credit pay table (Table Ln-GWC) 116 dictates the GWC earned as a function of player skill in the nth level of the game. The payouts governed by this table are dependent upon player skill and game play at large and may or may not be coupled to a random number generator. In several embodiments, game world credits (GWC) are player points earned or depleted as a function of player skill, i.e. as a function of player performance in the context of the game. GWC is analogous to the “score” in a typical video game. Each entertainment game has one or more scoring criterion, embedded within the Table Ln-GWC 116 that reflects player performance against the goal(s) of the game. GWC can be carried forward from one level of game play to another, and ultimately paid out in various manners such as directly in cash, or indirectly such as earning entrance into a sweepstakes drawing, or earning participation in, or victory in, a tournament with prizes. GWC may be stored on a player tracking card or in a network-based player tracking system, where the GWC is attributed to a specific player.

In certain embodiments, the operation of the GWE does not affect the RWE's gambling operation except for player choice parameters that are allowable in slot machines today including but not limited to the wager amount, how fast the player wants to play (by pressing a button or pulling the slot's handle) and/or agreement to wager into a bonus round. In this sense, the RWE 102 provides a fair and transparent, non-skill based gambling proposition co-processor to the GWE 112. In the illustrated embodiment, the communication link shown between the GWE 112 and the RWE 102 allows the GWE 112 to obtain information from the RWE 102 as to the amount of RWC available in the gambling game. The communication link can also convey a necessary status operation of the RWE (such as on-line or tilt). The communication link can further communicate the various gambling control factors which the RWE 102 uses as input, such as the number of RWC consumed per game or the player's election to enter a jackpot round. In FIG. 1A, the GWE 112 is also shown as connecting to the players user interface directly, as this may be necessary to communicate certain entertainment game club points, player status, control the selection of choices and messages which a player may find useful in order to adjust their entertainment game experience or understand their gambling status in the RWE 102.

In various embodiments, the ESE 120 manages and controls the visual, audio, and player control for the entertainment game. In certain embodiments, the ESE 120 accepts input from a player through a set of hand controls, and/or head, gesture, and/or eye tracking systems and outputs video, audio and/or other sensory output to a user interface. In many embodiments, the ESE 120 can exchange data with and accept control information from the GWE 112. In several embodiments an ESE 120 can be implement using a personal computer (PC), a Sony PlayStation® (a video game console developed by Sony Computer Entertainment of Tokyo Japan), or Microsoft Xbox® (a video game console developed by Microsoft Corporation of Redmond, Wash.) running a specific entertainment game software program. In numerous embodiments, an ESE can be an electromechanical game system of an anti-sandbagging hybrid game that is an electromechanical hybrid game. An electromechanical hybrid game executes an electromechanical game for player entertainment. The electromechanical game can be any game that utilizes both mechanical and electrical components, where the game operates as a combination of mechanical motions performed by at least one player or the electromechanical game itself. Various electromechanical hybrid games are discussed in Patent Cooperation Treaty Application No. PCT/US12/58156, filed Sep. 29, 2012, the contents of which are hereby incorporated by reference in their entirety.

The ESE 120 operates mostly independently from the GWE 112, except that via the interface, the GWE 112 may send certain GW game control parameters and elements to the ESE 120 to affect its play, such as (but not limited to) what level of character to be using, changing the difficulty level of the game, changing the type of gun or car in use, and/or requesting potions to become available or to be found by the character. These game control parameters and elements may be based on a gambling outcome of a gambling game that was triggered by an element in the entertainment game being acted upon by the player. The ESE 120 can accept this input from the GWE 112, make adjustments, and continue the play action all the while running seamlessly from the player's perspective. The ESE's operation is mostly skill based, except for where the ESE's algorithm may inject complexities into the game by chance in its normal operation to create unpredictability in the entertainment game. Utilizing this interface, the ESE 120 may also communicate player choices made in the game to the GWE 112, such as but not limited to selection of a different gun, and/or the player picking up a special potion in the GW environment. The GWE's job in this architecture, being interfaced thusly to the ESE 120, is to allow the transparent coupling of entertainment software to a fair and transparent random chance gambling game, providing a seamless perspective to the player that they are playing a typical popular entertainment game (which is skill based). In certain embodiments, the ESE 120 can be used to enable a wide range of games including but not limited to popular titles from arcade and home video games, such as but not limited to Gears of War (a third person shooter game developed by Epic Games of Cary, N.C.), Time Crisis (a shooter arcade game developed by Namco Ltd of Tokyo, Japan), or Madden Football (an American football video game developed by EA Tiburon of Maitland, Fla.). Providers of such software can provide the previously described interface by which the GWE 120 can request amendments to the operation of the ESE software in order to provide seamless and sensible operation as both a gambling game and an entertainment game.

In several embodiments, the RWE 102 can accept a trigger to run a gambling game in response to actions taken by the player in the entertainment game as conveyed by the ESE 120 to the GWE 112, or as triggered by the GWE 112 based on its algorithms, background to the overall game from the player's perspective, but can provide information to the GWE 112 to expose the player to certain aspects of the gambling game, such as (but not limited to) odds, amount of RWC in play, and amount of RWC available. The RWE 102 can accept modifications in the amount of RWC wagered on each individual gambling try, or the number of games per minute the RWE 102 can execute, entrance into a bonus round, and other factors, all the while these factors can take a different form than that of a typical slot machine. An example of a varying wager amount that the player can choose might be that they have decided to play with a more powerful character in the game, a more powerful gun, or a better car. These choices can increase or decrease the amount wagered per individual gambling game, in the same manner that a standard slot machine player may decide to wager more or less credits for each pull of the handle. In several embodiments, the RWE 102 can communicate a number of factors back and forth to the GWE 112, via an interface, such increase/decrease in wager being a function of the player's decision making as to their operational profile in the entertainment game (i.e. power of the character, gun selection, car choice, etc.). In this manner, the player is always in control of the per game wager amount, with the choice mapping to some parameter or component that is applicable to the entertainment game experience of the hybrid game. In a particular embodiment, the RWE 102 operation can be a game of chance running every 10 seconds where the amount wagered is communicated from the GWE 112 as a function of choices the player makes in the operation profile in the entertainment game such as those cited above.

In many embodiments, an anti-sandbagging hybrid game integrates a video game style gambling machine, where the gambling game (i.e. RWE 102 and RWC) is not player skill based, while at the same time allows players to use their skills to earn club points which a casino operator can translate to rewards, tournament opportunities and prizes for the players. The actual exchange of monetary funds earned or lost directly from gambling against a game of chance, such as a slot machine, is preserved. At the same time a rich environment of rewards to stimulate “garners” can be established with the entertainment game. In several embodiments, the anti-sandbagging hybrid game can leverage very popular titles with “garners” and provides a sea change environment for casinos to attract players with games that are more akin to the type of entertainment which a younger generation desires. In various embodiments, players can use their skill towards building and banking GWC which in turn can be used to win tournaments and various prizes as a function of their “gamer” prowess. Numerous embodiments minimize the underlying changes needed to the aforementioned entertainment software for the hybrid game to operate within an entertainment game construct, thus making a plethora of complex game titles and environments, rapid and inexpensive to deploy in a gambling environment.

In certain embodiments, anti-sandbagging hybrid games also allow players to gain entry into subsequent competitions through the accumulation of game world credits (GWC) that accrue as a function of the user's demonstrated skill at the game. These competitions can pit individual players or groups of players against one another and/or against the casino to win prizes based upon a combination of chance and skill. These competitions may be either asynchronous events, whereby players participate at a time and/or place of their choosing, or they may be synchronized events, whereby players participate at a specific time and/or venue.

In many embodiments, one or more players engage in playing an entertainment game, resident in the ESE, the outcomes of which are dependent at least in part on skill. The anti-sandbagging hybrid game can include an entertainment game that includes head-to-head play between a single player and the computer, between two or more players against one another, or multiple players playing against the computer and/or each other, as well as the process by which players bet on the outcome of the entertainment game. The entertainment game can also be a game where the player is not playing against the computer or any other player, such as in games where the player is effectively playing against himself or herself (such as but not limited to solitaire and babette).

In many embodiments, if an entertainment game includes a version of Madden Football™ for example, a player can bet on whether or not the player is going to beat the computer, or if the player is playing against another player, that other player. These bets can be made, for example, on the final outcome of the game, and/or the state of the game along various intermediary points (such as but not limited to the score at the end of the 1st quarter) and/or on various measures associated with the game (such as but not limited to the total offensive yards, number of turnovers, or number of sacks). Players can bet against one another, or engage the computer in a head to head competition in the context of their skill level in the entertainment game in question. As such, players can have a handicap associated with their player profile that describes their skill (which can be their “professed skill” in certain embodiments), and which is used by a GWE (such as a local GWE or a GWE that receives services from remote servers) to offer appropriate bets around the final and/or intermediate outcomes of the entertainment game, and/or to condition game play as a function of player skill, and/or to select players across one or more anti-sandbagging hybrid games to participate in head to head games and/or tournaments.

In such a scenario, assurances should be made to ensure that the player is not sandbagging, i.e. that the player has not previously performed below his actual skill level, in order to play in a future game with a lower skill rating and consequently have a better chance to win. For example, a highly skilled Scrabble® player might play ten games of Scrabble and intentionally garner mediocre scores so as to be handicapped as a “beginner”. This highly skilled player could then enter a “beginner” tournament, making a number of bets regarding the progress or outcome of the game, and in such tournament play at his true level of skill (i.e. “expert”), thereby giving him a substantial advantage over the true beginner players in the tournament. Such a player would be guilty of sandbagging.

Various embodiments include measures to prevent sandbagging in the context of hybrid games where the outcome of the game is in part or in whole determined by player skill and where betting as a function of skill-related performance and/or outcomes is permitted. Each of these embodiments can be used singularly or in conjunction with one or more of the other embodiments. Each of the embodiments is configured by the casino through the GWE (via an “anti-sandbagging module”) or a master anti-sandbagging server to which the relevant GWEs are subscribed. The GWE uses the anti-sandbagging software module to evaluate player performance against the player's professed skill level as represented by his handicap. It does this by comparing the player's performance during game play against the player's historical performance and/or the historical performance of players with similar handicaps. To the extent that the player's current performance exceeds his historical performance and/or the historical performance of his peers (vis-à-vis their handicaps) in a statistically meaningful way, the player is deemed to be sandbagging. In that event one or more of the below embodiments can be brought into force, having been parameterized previously by the casino as regards the severity with which the player's performance and/or status is to be affected.

In numerous embodiments, an anti-sandbagging module receives player performance measurements from the anti-sandbagging hybrid game and determines an appropriate skill level or ranking for the player based on those player performance metrics and initiates anti-sandbagging provisions as may be appropriate. Performance measurement data may include, but is not limited to, an outcome of the player playing the entertainment game, such as an expenditure, gain, loss or accumulation of GWC, player's experience points or the like (either as a rate or a total accumulation), a player's use of entertainment game resources such as EEs or AEs (either as a rate or an absolute amount) during one or more playing sessions, or a player's use, loss or accumulation of wagered credit resources, either real or virtual, (either as a rate or an absolute amount), etc. In addition, various other metrics may be derived from the performance measurement data, such as by determining a relationship, such as a ratio, between an outcome of the player's play of the entertainment game and a resource utilized by a player when playing the entertainment game. For example, determining the relationship of a rate of accumulation of GWC or other types of experience points by a rate of use of EE, credit, AE, etc. Other derivations may be determining a relationship between an accumulation of a GWC or other measure of experience by a total amount of a resource used, such as EEs, AEs, credits, etc.

Although various components of anti-sandbagging hybrid games are discussed above, anti-sandbagging hybrid games can be configured with any component appropriate to the requirements of a specific application in accordance with embodiments of the invention. Network connected anti-sandbagging hybrid games are discussed further below.

Network Connected Anti-Sandbagging Hybrid Games

Anti-sandbagging hybrid games in accordance with many embodiments of the invention can operate locally while being network connected to draw services from remote locations or to communicate with other anti-sandbagging hybrid games. In numerous embodiments, an anti-sandbagging module receives player performance measurements from one or more anti-sandbagging hybrid games and determines an appropriate skill level or ranking for the player based on those player performance metrics and initiates anti-sandbagging provisions as may be appropriate. In a case where two or more players wish to compete against each other in a head to head anti-sandbagging hybrid game, the anti-sandbagging module determines an appropriate anti-sandbagging provision for each player based on a comparison of the player's rankings to historical performance measurements for the players. A deployment diagram of an anti-sandbagging hybrid game in accordance with an embodiment of the invention is illustrated in FIG. 1B. In the diagram, an anti-sandbagging hybrid game 130 may be hosted by any computing device 132 capable of presenting interactive entertainment and gambling games to a player, such as (but not limited to) a land based or casino gaming machine, a personal computer, a gaming console, a wireless device such as a personal digital assistant, notepad computer, or smart phone. The anti-sandbagging hybrid games 130 may include a server 134 hosting an anti-sandbagging module connected with the various computing devices via a computer network, such as a local area network or a wide area network.

In many embodiments, operations associated with an anti-sandbagging hybrid game such as (but not limited to) processes for calculating score or RWC and GWC tracking can be performed across multiple devices. These multiple devices can be implemented using or in connection with a single server or a plurality of servers such that an anti-sandbagging hybrid game is executed as a system in a virtualized space, such as (but not limited to) where the RWE and GWE are large scale centralized servers “in the cloud” coupled to a plurality of widely distributed ESE controllers or clients via the Internet.

In many embodiments, an RWE server can perform certain functionalities of a RWE of an anti-sandbagging hybrid game. In certain embodiments, a RWE server includes a centralized odds engine which can generate random outcomes (such as but not limited to win/loss outcomes) for a gambling game, thereby eliminating the need to have that functionality of the RWE performed locally within the anti-sandbagging hybrid game. The RWE server can perform a number of simultaneous or pseudo-simultaneous runs in order to generate random outcomes for a variety of odds percentages that one or more networked anti-sandbagging hybrid games may require. In certain embodiments, an RWE of an anti-sandbagging hybrid game can send information to a RWE server including (but not limited to) Table Ln-RWC tables, maximum speed of play for a gambling game, gambling game monetary denominations or any promotional RWC provided by the operator of the anti-sandbagging hybrid game. In particular embodiments, a RWE server can send information to a RWE of an anti-sandbagging hybrid game including (but not limited to) RWC used in the gambling game, player account information or play activity and a profile associated with a player.

In several embodiments, a GWE server can perform the functionality of the GWE across various anti-sandbagging hybrid games. These functionalities can include (but are not limited to) providing a method for monitoring high scores on select groups of games, linking groups of games in order to join them in head to head tournaments, and acting as a tournament manager.

In a variety of embodiments, management of player account information can be performed by a GWE patron management server separate from a GWE server. A GWE patron management server can manage player account information, including (but not limited to) data concerning players' characters, players' game scores, players' RWC and GWC and managing tournament reservations. Although a GWE patron management server is discussed separate from a GWE server, in certain embodiments a GWE server also performs the functions of a GWE patron management server. In certain embodiments, a GWE of an anti-sandbagging hybrid game can send information to a GW patron management server including (but not limited to) GWC and RWC used in a game, player account information, play activity and profile information for players and synchronization information between a gambling game and an entertainment game or other aspects of an anti-sandbagging hybrid game. In particular embodiments, a GW patron management server can send information to a GWE of an anti-sandbagging hybrid game including (but not limited to) entertainment game title and type, tournament information, Table Ln-GWC tables, special offers, character or profile setup and synchronization information between a gambling game and an entertainment game or other aspects of an anti-sandbagging hybrid game.

In numerous embodiments, an ESE server provides a host for managing head-to-head play, operating on the network of ESEs which are connected to the ESE server by providing an environment where players can compete directly with one another and interact with other players. Although an ESE server is discussed separate from a GWE server, in certain embodiments a GWE server also performs the functions of an ESE server.

Servers connected via a network to implement anti-sandbagging hybrid games in accordance with many embodiments of the invention can communicate with each other to provide services utilized within an anti-sandbagging hybrid game. In several embodiments a RWE server can communicate with a GWE server. A RWE server can communicate with a GWE server to communicate any type of information as appropriate for a specific application, including (but not limited to): configure the various simultaneous or pseudo simultaneous odds engines executing in parallel within the RWE to accomplish the anti-sandbagging hybrid game system requirements, determine metrics of RWE performance such as random executions run and outcomes for tracking system performance, perform audits, provide operator reports, and request the results of a random run win/loss result for use of function operating within the GWE (such as where automatic drawings for prizes are a function of ESE performance).

In several embodiments a GWE server can communicate with an ESE server. A GWE server can communicate with an ESE server to communicate any type of information as appropriate for a specific application, including (but not limited to): the management of an ESE server by a GWE server such as the management of an anti-sandbagging hybrid game tournament. Typically a GWE (such as a GWE that runs within an anti-sandbagging hybrid game or on a GWE server) is not aware of the relationship of itself to the rest of a tournament since in a typical configuration the actual tournament play is managed by the ESE server. Therefore, management of an anti-sandbagging hybrid game tournament can include (but is not limited to) tasks such as: conducting tournaments according to system programming that can be coordinated by an operator of the anti-sandbagging hybrid game; allowing entry of a particular player into a tournament; communicating the number of players in a tournament and the status of the tournament (such as but not limited to the amount of surviving players, their status within the game, time remaining on the tournament); communicating the status of an ESE contained in a game; communicating the performance of its players within the tournament; communicating the scores of the various members in the tournament; and providing a synchronizing link to connect the GWEs in a tournament, with their respective ESE's.

In several embodiments a GWE server can communicate with a GW patron server. A GWE server can communicate with a GW patron server to communicate any type of information as appropriate for a specific application, including (but not limited to) information for configuring tournaments according to system programming conducted by an operator of an anti-sandbagging hybrid game, exchange of data necessary to link a player's profile to their ability to participate in various forms of game play (such as but not limited to the difficulty of play set by the GWE server or the GWE in the game they are playing on), determining a player's ability to participate in a tournament as a function of a player's characteristics (such as but not limited to a player's gaming prowess or other metrics used for tournament screening), configuring the game contained GWE and ESE performance to suit preferences of a player on a particular anti-sandbagging hybrid game, as recorded in their player account, determining a player's play and gambling performance for the purposes of marketing intelligence, and logging secondary drawing awards, tournament prizes, RWC and GWC into the player's account.

In many embodiments, the actual location of where various algorithms and functions are executed may be located either in the game contained devices (RWE, GWE, ESE), on the servers (RWE server, GWE server, or ESE server), or a combination of both. In particular embodiments, certain functions of a RWE server, GWE server, GW patron server or ESE server may operate on the local RWE, GWE or ESE contained with an anti-sandbagging hybrid game locally. In certain embodiments, a server is a server system including a plurality of servers, where software may be run on one or more physical devices. Similarly, in particular embodiments, multiple servers may be combined on a single physical device.

Anti-sandbagging hybrid games in accordance with many embodiments of the invention can be networked with remote servers in various configurations. A networked anti-sandbagging hybrid game in accordance with an embodiment of the invention is illustrated in FIG. 10. The networked anti-sandbagging hybrid game 160 is connected with a RWE server 162, GW patron management server 164, GWE server 166 and ESE server 168 over a network 170, such as (but not limited to) the Internet. Servers networked with a networked anti-sandbagging hybrid game 160 can also communicate with each of the components of a networked anti-sandbagging hybrid game and amongst the other servers in communication with the networked anti-sandbagging hybrid game 160.

Although various networked anti-sandbagging hybrid games are discussed above, networked anti-sandbagging hybrid games can be configured in any manner as appropriate to the requirements of a specific application in accordance with embodiments of the invention. Assignment of handicaps within anti-sandbagging hybrid games is discussed further below.

Assignment of Handicaps as Anti-Sandbagging Provisions

Anti-sandbagging hybrid games in accordance with many embodiments of the invention can provide the fairness of entertainment game play irrespective of player skill level by assigning handicaps as ant-sandbagging provisions to players based upon a player's performance measurements. An anti-sandbagging hybrid game includes a GWE that utilizes input from an anti-sandbagging module to implement the proper handicap to players to ensure fairness of entertainment game play. An anti-sandbagging module is able to assign handicaps based upon a player's ranking, and a player's ranking can be based upon performance measurements received from a GWE. A sequence diagram describing an anti-sandbagging hybrid game that assigns handicaps to players that can be dynamically adjusted by current play sessions in accordance with an embodiment of the invention is illustrated in FIG. 2. The timing diagram 200 includes an anti-sandbagging module 204 receiving (206) player performance measurements from a GWE 602 for a player. These performance measurements are stored as historical performance measurements to be used to evaluate the player's performance in a future playing session. In the same or subsequent playing session, additional player performance measurements are received (210) are received by the anti-sandbagging module 204. The anti-sandbagging module determines (212) if the player exceeded an expected player performance as described herein. If the player has exceeded the expected player performance, then a handicap as an anti-sandbagging provision is assigned to the player. The anti-sandbagging module then transmits (216) the assigned handicap to the GWE. The GWE then implements (220) the handicap during a player session, whether it be head-to-head or in solo play. Player performance measurements. The anti-sandbagging module also receives (222) information on player performance during the handicapped play sessions to determine (224) if the player significantly deviates from expected player performance in a statistically meaningful way. The information on player's performance can include current as well as historical player performance and can also include information on the particular player, other players or a group of players. If the player significantly deviates from the expected player performance in a statistically meaningful way, then the player's ranking can be adjusted (226) accordingly. In certain embodiments, the player's handicap is also adjusted according to the adjustment made to the player's ranking.

In some embodiments, the historical performance measurements are from players that are similarly ranked as the player being evaluated. That is, in the case that the player has asserted a particular ranking, the player may be evaluated to determine if the player has misstated their ranking by determining if the player's performance exceeded the player performance of similarly ranked players.

Randomness as Anti-Sandbagging Provision

The extent to which randomness, as opposed to skill, affects events in, or the outcome of, the entertainment game can be altered so as to reduce the impact of player skill relative to the impact of random events upon game play. In a shooting game, for example, the accuracy with which shots can be aimed at targets is a function of the aim of the player plus a random component that impacts the trajectory of the player's shot. The amount by which the trajectory is affected by the random component can be a small or large amount relative to the underlying accuracy with which the player actually aims the gun. The random component in this case can be thought of as a radius extending outward from the inherent aiming accuracy of the player, with the radius increasing to the extent which randomness is to play a greater role in determining the result of the shot, from a radius of zero to a radius much, much greater than the inherent accuracy of the player's aim.

In some embodiments, the introduction of randomness can be consistently applied across the game for all players participating in a game, or it can be applied independently as a function of each player's handicap (i.e. the measure of their skill in the game) on a player by player basis. The introduction of randomness can also be dynamically established during game play in response to an evaluation of the player's performance relative to historical norms for that player, or a population set of relevance (e.g. players with a similar handicap). If a player is outperforming his historical performance levels by a statistically significant margin as determined by the anti-sandbagging module, the amount of randomness introduced into the player action(s) under consideration will be increased on the fly, until such time as the player's performance in the game aligns more closely with the performance expected as a function of the player's professed skill level (i.e. his handicap).

Another example of using randomness as a handicap would be to introduce error in the steering (analogous to a “loose” steering system) of a race car game for the player who has been deemed by the anti-sandbagging system to be operating outside normal level ranges (in a statistically significant way) of play given the player's professed level of skill.

Scoring as Anti-Sandbagging Provision

Conventionally, games utilize an absolute scoring system to evaluate performance of the player. As a mechanism to preclude sandbagging, the invention allows for a relative scoring system to be utilized, such that the amount of GWC that a player accumulates during a game and at its conclusion, as a function of various actions and/or achievements, is scaled as a function of one of a number of factors. Factors that can algorithmically modify the baseline (i.e. absolute) scoring system (inclusive of the game's modifications to scoring as a function of level of difficulty and/or other variables) resident in the game include, but are not limited to the following.

In some embodiments, a modifier to the score is applied as a function of player skill—either demonstrated in the immediate context of the game or based upon prior performance within the game or prior game play sessions. To do so, a modifier to the score as a function of the player's performance in the game relative to his expected performance based upon a previously established handicap as established by the anti-sandbagging module

Through the use of one or more such modifiers, a skilled player is in effect discouraged from sandbagging because his score can be retarded as a function of demonstrated performance superior to expected or professed capability. For example, in a game of pop-a-shot, two players enter a head-to-head tournament professing to be “Beginners” (meaning in this case they are likely to hit less than 40% of their shots), information contained within their player profile. In reality one of these players, Player B, is “Advanced”, meaning he can hit over 70% of his shots in the game, but he has sandbagged his previous playing of the game to trick the system into believing he is a Beginner. The game is slated to take four minutes. During the first minute, the game calculates that Player B is hitting 75% of his shots, and determines, by comparing this performance against the historical performance of legitimate beginner players during the first minute of play, that this performance is, statistically speaking, only 10% likely to represent the play of an actual beginner player. As a result, subsequent baskets made by player B, instead of being worth 10 points are worth a lesser amount. In this example, they are now worth only four points, which corresponds to a score that would drive player B to a number of points equivalent to the median of “Beginner” players (i.e. hitting 75% of his shots at 40% of the nominal score makes each attempt worth three points, which would be equivalent to a Beginner player hitting 30% of his shots).

In many embodiments, this process could be revisited continuously throughout game play, periodically, or a single time as a function of set up parameters controlled by the Casino via the anti-sandbagging module of the GWE of the anti-sandbagging hybrid game. The algorithmic modification of the score can take as arguments not only the aforementioned evaluation of skill and the players'professed skill, but can also take into account the gap in score between the player or players relative to each other, or a historical record of score history for the players themselves or a class of players to which they each belong (i.e. “Beginner”, players who have played in excess of twenty times, players over 65 and with less than twenty plays, etc.). As such, the anti-sandbagging hybrid game can modify a player's score downwards or upwards more or less via the aforementioned mechanisms (and others) to ensure that the game remains “close”.

Bet Value Limits as Anti-Sandbagging Provision

In another embodiment, the anti-sandbagging hybrid game enforces limits on the value of bets that can be placed, and/or the amount that can be won, by players as a function of the professed skill level of one or more of the players, these limits being established by the casino or operator. Generally speaking, the amount that can be bet on a game, an intermediate outcome of a game, or an intermediate or final characteristic of the game would be limited. Limiting the amount that can be wagered in this way dissuades high skill players from masquerading as lower skill players because the amount of money they can win is less. This functionality, configured by the casino or operator via the anti-sandbagging function within the GWE, can take a number of forms, including, but not limited to, the following.

Maximum bets limited for all players as a function of the lowest professed skill level of all players in the game. For example if two players are going to be competing in a football game, the lower skill level player's level (e.g. “high school”, “college”, “pro” might be the levels used to grade players in the context of the football game) will govern the maximum bet that can be made for each available wager between the players.

Bet Volume Limits as Anti-Sandbagging Provision

In another embodiment, the anti-sandbagging hybrid game enforces limits on the number of bets that can be placed, and/or the aggregate value of bets placed and/or the aggregate value of bets won, by players over time as a function of the professed skill level of one or more of the players, these limits being established by the casino. This functionality can take a number of forms, including, but not limited to, the following or some combination thereof.

Maximum number of bets a player can place over a fixed period of time, or a fixed number of game plays, or in the absolute. This cap may be applied in the context of the player's professed skill level as recorded in their player profile, such that if the player moves up or down a skill level the cap can be periodically reset.

Maximum number of bets a player can win over a fixed period of time, or a fixed number of game plays, or in the absolute. This cap may be applied in the context of the player's professed skill level as recorded in their player profile, such that if the player moves up or down a skill level the cap can be reset.

Maximum value of bets a player can place over a fixed period of time, or a fixed number of game plays, or in the absolute. This cap may be applied in the context of the player's professed skill level as recorded in their player profile, such that if the player moves up or down a skill level the cap can be reset.

Maximum value of bets a player can win over a fixed period of time, or a fixed number of game plays, or in the absolute. This cap may be applied in the context of the player's professed skill level as recorded in their player profile, such that if the player moves up or down a skill level the cap can be reset.

Penalty Assessment as Anti-Sandbagging Provision

In another embodiment, the anti-sandbagging hybrid game prevents sandbagging by monitoring player performance in the anti-sandbagging hybrid game against the historical performance of all players of the same overarching skill level, and/or a representative but static data set of similar information and/or against the player's own historical performance. The GWE anti-sandbagging module (or a server based version of the anti-sandbagging module interfacing to a number of GWEs) utilizes statistical methods to establish, to a prescribed confidence interval, whether the player's performance in the game suggests that the player is of a higher skill level than the professed skill level of the player as recorded within his player profile. A counter is maintained in the player's profile as to the number of times that the player's performance exceeds the statistically expected performance for a player of the professed skill level. When the counter reaches a certain level (A), a warning may be issued to the player. The counter may reflect (non-comprehensively) the number of individual game sessions in which sandbagging was identified, or the number of specific intervals (e.g. time or levels) of game play in which sandbagging was identified, or the number of times sandbagging occurred and a bet over a certain amount was won, or a combination of these factors, etc. When the counter reaches a second threshold (equal to or greater to the level A), (B), the player may have his account flagged for manual review and a higher level of go-forward scrutiny, and his skill level ratcheted up one level. At a third threshold (C), the player's account may be temporarily suspended, and at a fourth threshold (D) the account may be permanently closed and the individual behind the account precluded from participating in subsequent activities within the game in question, the casino in question and/or the casino group in question. The thresholds A through D may be coincident or reflect a step-wise (but not necessarily linear) increase in the counter, and a variety of different punitive actions (distinct from the exemplary list above) may be implemented. The withholding of winnings, reduction of winnings, or the assessment of penalties or fines (against a deposit that could, for example, be required by players to participate in the skill based wagering aspect of anti-sandbagging hybrid game play) can accompany crossing one or more of the thresholds A through D.

Note also that the such an embodiment is not limited expressly to four levels of punitive action, but that any number from 1 to n may be included as part of the Penalty Assessment construct. Generally speaking, the penalty assessment methodology establishes a series of penalty thresholds. For each threshold a specific punitive action is prescribed. Penalty thresholds are reached as a function of the player having been found to be sandbagging a certain number of times. The counter used to establish whether a threshold has been crossed can track one or more measures of sandbagging frequency within a single counter (i.e. each game in which a player sandbags across multiple game titles can be tracked singularly), or multiple counters can be used in parallel across different games or to measure sandbagging along multiple dimensions within a single game, each triggering thresholds independently.

For example, consider a first person shooter game, where a player professes to be of intermediate skill, but actually has the capabilities of an expert. Having sandbagged for a number of games to establish his skill as intermediate he enters into a head-to-head competition with a truly intermediate player, and then plays to the fullest of his ability. The GWE anti-sandbagging module compares the accuracy of the player's shooting over a period of twenty shots against the distribution of accuracy for players graded as intermediate and determines with a high degree of statistical confidence that the player is in fact not an intermediate player. The counter increases from 0 to 1, and in this case threshold A is crossed at a count of “one instance where the player's shooting accuracy is statistically such that it is not of an intermediate level”. A warning is issued to the player and game play continues. Two more samples of twenty shots are evaluated subsequently, and because the determination is made that the player is still performing at a level significantly above that of an intermediate player the counter has incremented to three, and threshold B is crossed, causing the player's account to be flagged for review, a second warning issued, and the player's professed skill as recorded in his profile to be elevated to “expert” for subsequent game play.

In some embodiments, the aforementioned counter is maintained until a resetting event takes place, such as a certain number of game plays or a certain amount of elapsed time without any increase in the counter.

Note also that the penalties assessed can be “outside” the entertainment game (e.g. suspension of a player's account, disgorgement of winnings, resetting the player's handicap to a higher level), or “inside” the entertainment game (e.g. player's character is severely injured by stepping on a land mine, the player's gun jams, the player's football team is assessed a penalty and loss of down in a football game, etc.).

Reducing the Benefits of Skill Via the Introduction of Deterministic Errors as Anti-Sandbagging Provision

In some embodiments, performance in the context of the entertainment game is a function of both player skill and a certain degree of randomness introduced during game play. To address perceived sandbagging (as measured in the manner previously described, i.e. a statistically significant deviation of current player performance relative to a standard or norm) a deterministic (instead of random) error (which need not be a static value) is injected into the entertainment game. For example, in a first person shooter game, if the anti-sandbagging module determines that the player is sandbagging, a deterministic error in the player's aim can be introduced into the data encapsulating the aim of the weapon generated in the entertainment game when the player fires his weapon, before such data is used by the game to establish whether the target was hit. The introduction of this inaccuracy can take place between the player's game controller and the ESE, or within the ESE itself (as a function of a flag set by the GWE or other means), after data from the controller has been received.

While it is possible for the player to ultimately compensate for deterministic errors, they still have the effect of causing the player to perform at a lower level than otherwise for a period of time.

In various embodiments, the amount of error introduced (or its vector) can be altered over time as a function of the current status of the player's performance relative to his professed skill. In this way a feedback loop is at work, continuously adjusting the vector of the error introduced until the player's measured performance is in line with expected norms given his professed skill level.

Ringer Detection as Anti-Sandbagging Provision

Another form of sandbagging consists of players introducing “ringers” i.e. imposters whose pretense is intended to gain an advantage in competition, as replacements in head-to-head and/or tournament play. For example, an intermediately skilled Scrabble® player may be ranked appropriately, but allow a highly skilled player to use his account, making a number of bets regarding the progress or outcome of the game, and in such tournament play at his true level of skill (i.e. “expert”), thereby giving him a substantial advantage over the true beginner players in the tournament. Such a player would be guilty of using a ringer. Linking an individual player to a specific account prevents ringers.

In some embodiments, the anti-sandbagging module uses biometric identification methods. In order to confirm the identity of the player and to prevent a player from re-enrolling under a different name, player names and/or accounts are linked to specific biometric measurements. Such measurements could include but are not limited to: retinal scans, iris recognition, fingerprints, palm prints, facial/image recognition, and voice prints. These measurements could be used for both positive and negative biometric identification. Initial measurements may be taken during account set-up, when first engaging in gameplay, or when issued a unique ID such as a ticket, code, or other means for anonymous play. Biometric data would “travel with” any unique ID or account.

In many embodiments, players confirm biometric identification as soon as a he logs into an account or starts gameplay. If a player fails to provide accurate biometric measurements, the anti-sandbagging module may first issue a warning and allow the player to submit measurements again. Further failures subject players to the penalty assessments described above.

In numerous embodiments, biometric identification methods are used when the anti-sandbagging module alerts the operator that play is inconsistent with past performances. Gameplay may pause, requiring the player to immediately submit to biometric identification. Alternatively, the anti-sandbagging module may periodically take unobtrusive biometric measurements to confirm identification throughout gameplay. Failure to provide accurate biometric measurements subjects players to the penalty assessments described above.

In some embodiments of individual recognition, the player may be required to answer specific questions. These can include security questions established at account creation, questions regarding past performances, questions about account set-up date, etc. Failure to provide accurate answers subjects players to the penalty assessments described above.

In numerous embodiments, player geographic location or IP addresses may be tracked. Changes in either may subject players to a higher degree of scrutiny or the penalty assessments described above.

Accommodating Improving Skills

In an anti-sandbagging hybrid game, performance in the context of the entertainment game is a function of both player skill and a certain degree of randomness introduced during game play. However, player skill level is not necessarily a fixed factor. As players experience the game, their skill levels may measurably improve (a beginner player becomes an intermediate player, and so on). Such an increase of skill could expose a player to censure by the anti-sandbagging module. To avoid penalizing players gaining skill rather than sandbagging, in some embodiments, upon detection that a player has improved progressively over recorded levels, the anti-sandbagging module could allow for raising the expected level of the player. Alternatively, players could self-report increases of skill and thus increase expected performances before engaging in play.

In various embodiments, at the onset of any game session the player is informed by the system as to their professed skill (if one is on record at all), and asked to confirm or alter the skill level. If no professed skill (handicap) is on record, the player selects the skill level they believe to be appropriate. This notification could be incorporated into player/account selection at the start of gameplay rather than as a separate event.

In many embodiments, there is a short period at the onset of gameplay during which the anti-sandbagging module assesses player skill level and evaluates whether the professed skill level matches demonstrated skill. If there is a disparity, the hybrid game is paused and a player is given the option to alter his skill rating. This allows the player to more accurately self-report skill level and skill level changes.

In some embodiments, a player can use the anti-sandbagging hybrid game in a mode (for a short period of time and for free) whereby they are “tested” to establish an updated handicap. This mode would be finite rather than the beginning of gameplay.

In numerous embodiments, a player can, at any time, interface with the UI of a suitably configured anti-sandbagging hybrid game, a dedicated terminal, and/or a person operating a dedicated terminal or application, to report in with a new skill level.

In many embodiments, a player is “tested” for actual v. professed skill periodically, (e.g. day, week, month, every X game plays) through free game play or as part of the player's paid game play (during which time the player may or may not be engaged in head-to-head competition, and may or may not be permitted to gamble).

These embodiments may or may not require participation in a player club. When a player club is unavailable or a player elects not to participate in one, the player is still identified. Rather than linked explicitly to a specific account, the player is anonymously tracked, via the use of a ticket, code, or other means by which he is given a unique ID that persists but is not tied to his person (i.e. not linked specifically to his name, etc.).

The process of initiating an anti-sandbagging provision has been described as taking place within the GWE anti-sandbagging module. The anti-sandbagging module interacts with the ESE to implement the aforementioned embodiments. The GWE anti-sandbagging module communicates with the ESE to cause the ESE to alter the entertainment game environment and/or game play to impose penalties as necessary. Certain embodiments, such as bet volume limits, do not invoke this GWE-ESE interaction, but others, such as the introduction of random or deterministic errors require handshaking between the GWE and ESE to affect the penalty or penalties.

Although various anti-sandbagging hybrid games constructed to assign handicaps to players are discussed above, anti-sandbagging hybrid games can be constructed to assign handicaps as anti-sandbagging provisions in any manner as appropriate to the requirements of a specific application in accordance with embodiments of the invention. Assignment of rank in anti-sandbagging hybrid games are discussed further below.

Rank Assignments

Performance in the context of the entertainment game in accordance with many embodiments of the invention is a function of both player skill and a certain degree of randomness introduced during entertainment game play. In order to apply the correct handicap, a player's skill level is ranked. As a player's skill level increases or decreases, the player's overall rank, and therefore handicap, can be adjusted to reflect the change in player skill level. Additionally, a player's skill level at a particular entertainment game may not be related to the player's skill level at other entertainment games. For example, success in a racing type entertainment game may not be indicative of the player's skill level in a shooting type entertainment game. However, a player's skill level in one game may be related to a player's skill level in a related game, such as sequels to the same entertainment game.

In many embodiments, a player may be ranked depending on the ratings of the player's opponents, and the results of the player's play against the opponents. In certain embodiments, the relative difference in rating between two players determines an estimate for the expected score between them. The design of the ranking system, including the range and mean rank may be chosen by the operator as appropriate for the anti-sandbagging hybrid game. Thereby, rankings are calculated based on the strength of a player's opponent and the actual results of the game play between the players. This system, where performance is not measured absolutely, allows handicapping inferred from wins, losses, and draws against other players. If a player wins a game, the player is assumed to perform at a higher level than his opponent for that game. Conversely if a player loses, the player is assumed to perform at a lower level than the opponent. If the game is a draw, the two players are assumed to perform at nearly the same skill level.

In several embodiments, these rankings are then used to predict performance so handicapping can be applied. When a player's results exceed the player's expected scores, the system takes this as evidence that a player's ranking is too low, and can be adjusted upward. Similarly when a player's actual results fall short of the player's expected scores, that player's ranking can be adjusted downward. The anti-sandbagging module may use a simple linear adjustment proportional to the amount by which a player over performed or underperformed the expected score. This type of system can be used in a variety of entertainment games. Additionally, this rating can be applied when a player's performance is measured over time, rather than during play of single gaming session. The adjustment mechanism may also include a “deadband” or weighting functionality such that the player's rating is not immediately adjusted solely as a function of a single or recent performance(s), but rather considers recent results in the context of a broader set of player performance data.

In numerous embodiments, different rankings can be divided into “bands of skill,” (similar but not the same as the popular chess ranking system Elo, where a player with an Elorating from 2000-2199 may be considered an expert, while a rating from 600-799 may be considered a beginner). This allows a general handicap to be assigned to different skill bands rather than to individual ranks depending on the entertainment game in question.

In a variety of embodiments, players are placed on a “ladder” and each player is assigned a numerical value that shows how skilled the player is at a certain game. The ladder system proceeds via a system of challenges. Head to head games may occur on a scheduled or ad hoc basis between different rungs on the ladder. In ad hoc play, a first player may challenge a player at a higher level on the ladder. In certain embodiments, refusing a challenge may lead to penalties for the refusing player (such as but not limited to reduction in rank, and/or being barred from tournaments). If the low-ranked player wins the match, then the two players swap places on the ladder or are moved up and down a certain number of “rungs” on the ladder (which may also affect the position of other players between the two rungs initially occupied by the two players). If the low ranked player loses, then that player may be banned from challenging the same person again without challenging someone else first. There may be a limit as to how many rungs above themselves players may challenge. Initial placement on the ladder may be random or deterministic based upon an entry test/challenge.

In a number of embodiments, player ranking may be assigned on level based progression. A player can accumulate experience points (XP) based on play time, tasks undertaken, skills learned and/or a variety of other criterion. To “level” or “level up,” a player gains enough XP to reach the next level. When a level is gained, the player's abilities or statistics increase, making the player stronger. In a number of embodiments, a player's ranking is based (at least in part) on the level attained by the player, and a handicap assigned accordingly.

In many embodiments, skill level may be assigned based on performance in specific aspects of the game. In certain embodiments involving a hunting game, factors including but not limited to accuracy, type of animals killed, and kill quantities may be valued separately and then combined to provide the overall ranking. In particular embodiments, skill level is not necessarily based on wins/loses, and handicapping may be applied based on specific aspects of the game (a skilled player in each aspect of the above hunting game may be handicapped with features such as, but not limited to, less accurate guns, fewer numbers of animals, or more difficult kill-shots).

In several embodiments, there can be a short period at the onset of game play during which the anti-sandbagging module assesses player's current skill level and evaluates that skill level relative to the player's historical skill level(s) before applying the appropriate handicap. In a number of embodiments, the anti-sandbagging module assesses player skill level throughout game play to evaluate the player's skill level. The anti-sandbagging module may then apply the appropriate handicap at the conclusion of the game play session.

In various embodiments, a player can use an anti-sandbagging hybrid game in a mode (such as for a short period of time and/or without payment) whereby the player is “tested” to establish a skill rating. This mode can be finite rather than at the beginning of gameplay. Also, this test mode can be distinct from actual gameplay.

In numerous embodiments, if no professed skill is on record, players may select the skill level they believe to be appropriate. This selection could be incorporated into player/account selection at the start of gameplay rather than as a separate event. As play continues, the player's performance is measured and compared to others of the professed skill level. Where there are discrepancies, the rating assigned and the handicap applied is adjusted. Alternatively, players that estimate their performance inaccurately may be disqualified from play.

In several embodiments, ranking systems can implement skill floors for individual players. A skill floor is the minimum ranking that a player can fall to. For instance, if a player has an established ranking of “expert”, subsequent poor performances cannot reduce his ranking to “beginner.” However, depending on the hybrid game in question, an “expert” player may have his or her rank decreased to an “intermediate player,” depending on the skill floor assigned. A skill floor may be assigned according to any arbitrary criteria, including but not limited to the number of games played, amount of money won, amount of games won, and/or additional factors that can be used establish a player's skill level.

Several embodiments may or may not require participation in a player club. When a player club is unavailable or a player elects not to participate in one, the player is still identified. Rather than linked explicitly to a specific account, the player is anonymously tracked, via the use of a ticket, code, or other means by which a player is given a unique ID that persists but is not tied to a player's person (such as but not limited to not being linked specifically to the player's name).

In numerous embodiments, rankings may be continuous or discrete. Rankings may be specific to the casino, the casino family, and/or geographic location or other divisions. The anti-sandbagging module may function to normalize disparate rankings or rankings across multiple systems and locations.

A process flow diagram of a process for determining if a player's current performance at an anti-sandbagging hybrid game exceeds historical performance in accordance with an embodiment of the invention is illustrated in FIG. 3A. The process 300 includes an anti-sandbagging module retrieving current player performance measurements (502) and historical performance measurements (504) for a player while playing an anti-sandbagging hybrid game. The historical performance measurements are for the particular player's historical performance measurements. The order in which current player performance measurements and historical performance measurements are retrieved is non-limiting and can be retrieved in any order. The anti-sandbagging module then performs (206) statistical analysis upon the current player performance measurements and historical performance measurements. If there is sufficient deviation from expected performance measurements as defined in sandbagging definitions 507, then the player's rankings and corresponding handicaps as anti-sandbagging provisions can be adjusted (508) according to any of the anti-sandbagging provisions described herein and as specified by an operator's anti-sandbagging parameters 509. In various embodiments, the player's ranking, and subsequent handicap, may be re-ranked upward to a higher rank. However, if the currently player's performance measurement information indicates a poorer quality of fair play during the current play session, the player's rank, and subsequent handicap, may be adjusted to a lower value.

In many embodiments, an outlier test is used to determine if the player's current performance information indicates that the player has significantly deviated from expected performance. In certain embodiments, an outlier test such as (but not limited to) the Grubb's outlier test can be used. The Grubb's outlier test can be used to detect outliers in a data set assumed to come from a normally distributed population. To perform the Grubb test, a value T is calculated:

T=Abs(Xi−Xmean)/s

where:

Abs( )=absolute value function;

Xi=observed player performance measurements for a current play session;

Xmean=mean of historical player performance measurements for previous play sessions; and

s=standard deviation of Xmean.

Once T is calculated, a lookup table is used to determine the probability that a rejection of Xi as belonging to the population of Xmean is improper. For example, the lookup table illustrated in FIG. 3B can be utilized. In FIG. 3B, the headings represent the probability, in percentages, that a rejection is improper, and N is the number of sampled historical data points for player performance that were used to calculate Xmean.

In other embodiments, any technique for determining whether player performance is inconsistent with past performance can be utilized as appropriate to the requirements of a specific anti-sandbagging hybrid game.

The table is used by looking up the value of Tin the table for the number N samples. Then, the probability is determined by looking up the column to the probability value featured in the header. For example, if N=20 sampled player performance measurements and T is calculated to be 2.71, then the rejection of Xi as not belonging to the population of the sampled player performance measurements has a 2.5% chance of being improper. Put another way, there is a 97.5% chance the particular instance of player performance is proper.

In several embodiments, outlier tests such as (but not limited to) Dixon's Q-test are used. In a Dixon Q-test, a ratio of distance between a tested value and its next closest value in a set of sampled values as compared to the range of all values in the sample is used to determine if the tested value comes from the same population as the set of sampled values. In certain embodiments, a process for determining a Q-test is as follows.

The sampled values of historical player performance measurements are arranged in ascending order:

x ₁ <x ₂ < . . . <x _(N)

A ratio, Q_(exp), is calculated as the difference between the value of the currently player performance measurement, X_(N), being tested from its nearest neighbor value, X_(N-1), divided by the range of the values of player performances:

$Q_{\exp} = \frac{X_{2} - X_{1}}{X_{N} - X_{1}}$ $Q_{\exp} = \frac{X_{N} - X_{N - 1}}{X_{N} - X_{1}}$

The obtained Q_(exp) value is compared to a critical Q-value (Q_(crit)) found in the table containing the critical Q values produced below. If Q_(exp)>Q_(crit) for a particular confidence interval, then the tested player performance value can be characterized as an outlier, that is, that the current player performance measurement may significantly deviate from expected player performance measurements in a statistically meaningful way.

A table containing the critical Q values for confidence level (CL) 90%, 95% and 99% and N=3-10 is given below:

Table of critical values of Q Q_(crit) Q_(crit) Q_(crit) N (CL: 90%) (CL: 95%) (CL: 99%) 3 0.941 0.970 0.994 4 0.765 0.829 0.926 5 0.642 0.710 0.821 6 0.560 0.625 0.740 7 0.507 0.568 0.680 8 0.468 0.526 0.634 9 0.437 0.493 0.598 10 0.412 0.466 0.568

In certain embodiments, the expected performance can be the player's own historical performance while playing a particular hybrid game. In particular embodiments, the expected performance can be the performance of other players having the same or similar ranking as the player in question for a particular hybrid game.

Although various anti-sandbagging hybrid games constructed to evaluate the rank of players are discussed above, anti-sandbagging hybrid games can be constructed to evaluate rank in any manner as appropriate to the requirements of a specific application in accordance with embodiments of the invention.

A sequence diagram illustrating the operation of an anti-sandbagging hybrid game that assigns handicaps as anti-sandbagging provisions according to player skill level in accordance with an embodiment of the invention is illustrated in FIG. 4. The sequence diagram 400 includes interactions between one or more GWEs 402 of one or more anti-sandbagging hybrid games and an anti-sandbagging module 404. The sequence includes an anti-sandbagging module receiving (406) player performance measurements for each player 1 to N from one or more GWEs 402 and determining (408) if each player 1 to N exceeded their respective expected performance based upon how each player's performance measurements are related to respective historical performance measurements of the player. As the players are evaluated for sandbagging, appropriate handicaps are assigned (414) for each of the players based upon the determination of sandbagging for each player. The anti-sandbagging module then returns (418) instructions to apply appropriate handicaps as anti-sandbagging provisions or each player to the one or more GWEs and the GWEs implement (220) the handicaps as appropriate.

A sequence diagram illustrating the operation of an anti-sandbagging hybrid game that adjusts a player's ranking dynamically in accordance with an embodiment of the invention is illustrated in FIG. 5. The anti-sandbagging module 504 receives (506) player performance measurements from a GWE 502 and assigns (508) a player ranking based upon the player performance measurements. Then, the anti-sandbagging module 504 receives (510) player performance measurements from subsequent sessions of entertainment game play after the initial ranking was assigned. The anti-sandbagging module 504 can analyze the subsequent performance measurements to determine (512) if the player significantly deviated from expected player performance and adjust (514) the player's rankings and handicaps applied as ant-sandbagging provisions in light of the significant deviation.

Although various anti-sandbagging hybrid games constructed to assign rank to players are discussed above, anti-sandbagging hybrid games can be constructed to assign rank in any manner as appropriate to the requirements of a specific application in accordance with embodiments of the invention.
